Chart revenue from new, upgrading, renewing and returning subscribers, then explain each spike

Surfaces which past decisions moved revenue, e.g. a lifetime plan launch; no numbers

What they did

When starting in a revenue role (Babbel, then Yousician), split subscription revenue into four buckets: new subscribers, upgrades between plans, renewals, and win-backs (churned users who return). Track how each bucket evolves over the years in Excel, find the big jumps or drops (e.g. new-subscriber revenue jumping from a given month), then ask what happened and map it to the decision (e.g. launching a lifetime subscription). Link or embed the documentation of each decision in the same spreadsheet and turn it into a short presentation to share. Prefer this over reading every entry of a long experiment log, since many experiments don't matter.

What happened

Reveals which decisions actually moved the business and prevents re-learning past lessons; no quantified result.
“You can either get money from people that never had the subscription and start a new subscription, people that upgraded from a subscription to another, people that renew a subscription or people that used to have subscription then churned and then came back. So these four buckets, you have these four buckets.”
Sara Grana
“I would track in Excel how we're moving, and then from that, maybe have a little presentation for me or then to share and then you map, okay, "Here, this line, this happened because of this thing."”
